Abstract

The polarisation converter is for use with a Photonic Band Gap waveguide in which the waveguide comprises a host material having a first refractive index n1, bounded at least in part by host material (9) containing a plurality of inserts (10) each having a second different refractive index n2. The converter comprises a region (11a) of the waveguide in which incident radiation is resolved into different eigenmodes each of which propagates at such a different velocity as to introduce progressively a phase shift between the modes. The length of the region is such as to cause a predetermined phase shift, preferably of TT.
